With this electronic fishing rod, you can fish on winter fishing.Do not be confused with another fishing rod, which is prohibited by law, this device is quite harmless and legal, there are similar electronic fishing rods on sale on the Internet.
The basis of the fishing rod is a solenoid that will make movements up and down.I took it and the printer, they are usually used there, but you can make a solenoid yourself.This is an inductor with a metal core, when a current passes through the coil, an electromagnetic field is formed that attracts a metal armature to the core.The force of attraction and repulsion is regulated by a spring.
A whip is installed on the anchor, I left the coil resistance about 30 ohms.
The frequency of the whip movement depends on the supply voltage, the capacitance of the capacitor C1 and the resistance of the alternating resistor.Frequent fluctuations of the whip will be at a capacitor capacity of 4.7 uF and a power supply of about 4 Volts, less often and more powerful will be at 10 uF and with a power supply of 6 Volts.
